Application January 25, 1936, Serial No..60,830

Claims.

My invention relates to a combination structure employed with the twist wringing type of mop.

Among the objects of my invention is to create a wringing mechanism having a brake interrupter and a swab holder lock each actuated by a single intermediary resilient member, and such other objects, advantages and capabilities as will later more fully appear and which are inherently possessed by my invention.

While I have shown in the accompanying drawing a preferred embodiment of my invention yet I wish it understood that the same is susceptible of modification and change without departing from the spirit of my invention. I

Referring more'particularly tothe drawing, Fig. 1 is a perspective view of a Wringer mop using my combination wringing mechanism and swab.

holder; Fig. 2 is a more detailed view of my structure, and Figs. 3 and 4 are detailed views of the interrupter, spring and swabrholder lock.

My wringer mop comprises an elongated handle I 0, a torque arm structure I I, a wringing mechanism I2, a swab holder l3 connected to the bot- .tom of, the handle l0 and a swab 14 extending between the swab holder l3-and the wringing mechanism l2. V

A U shaped member I! is supported on a hearing it of the torque arm 15. .The U shaped member l1 acts as a bearing for the twisting shaft 24 which passes transversely through both'glegs of the U shaped member soas to prevent vertical displacement of said U shaped member. Means such as opllositely' disposed fiares 25 are fixed to the twisting shaft 24 against the U shaped member I! Y to prevent lateral displacement of said twisting shaft 24.

The U shaped member I! has on one face a plurality of integral interruptions 26 such as humps, depressions or the like.

A disk 21 is slidably keyed to the twisting shaft 24 and has a plurality of integral interruptions 28, such as humps, depressions or the like, such interruptions spaced to correspond with the successive twists of the wrist of an operator in twisting the wringing mechanism. Said disk 21 is placed opposite said U shaped member I! so that upon rotation of the twisting shaft 24 the interruptions 28 of the disk 27 engage the interruptions 26 of the U shaped member I1.

The twisting shaft 24 continues below the disk 21 and terminates in a loop 29 adapted to hold a swab 14. The loop 29 has an opening 30 which is normally covered by a locking member 3|. Said locking member 3| is U shaped so that its bottom portion straddles one leg of said loop 29 and is slidable thereon. A pin 32 passing transversely through both legs of the U shaped locking member and over said leg of the loop prevents displacement of the locking member, acts as a stop for lateral movement of the locking member and holds 5 the locking member from flaring when the mop is twisted and thus reinforces the loop, preventing it from twisting out of shape or straightening.

In the upper edges of each of the legs of the locking member, preferably substantially at the middle thereof, is a recess 33.

A resilient member 34, such as a coiled spring or the like, surrounds the twisting shaft 24 and is interposed between'the disk 21 and the locking member 3| so that one end of the spring 34 engages the disk 21 and the other end of said spring 34 fits into the recess 33 of the locking member 3|, when the locking member 3! is in closed position.

In order to permit the locking member 3| to move,

it isnecessary for an operator to first lift the 2 spring 34 out of therecess .33. When this has been done, the locking member 3| can then be moved was to expose an opening of the loop 29 for the insertion and withdrawal of the swab l4. My resilient member 34 being interposed between the disk and the locking member performs a double function in that it exerts pressure on both the disk and the locking member, the pressure on the disk causing interrupted function and the pressure on the locking member retaining the looking member infixed closed position.

My patent, No. 2,018,413 of October 23,1935, shows andclaims atorque arm construction, a wringing mechanism, a ratchet and a selector. My copending application, Ser. No. 32,525, claims '35 a torque. arm construction in which a retaining rod is slidable with respect to the handle. My copending application 45,298, relates to a torque arm structure for holding the wringing mechanism and the swab in fixed wringing position. 40 My copending application, Ser. No. 60,829, claims a pivot arm lock.

My present invention is new and different from the above patents and copending applications in that in this case I disclose and claim a combination wringing mechanism and swab holder lock for wringer mops not shown, described or claimed in my previous patents and applications.

Having thus described my invention, I claim:

1. A device of the class described comprising a member, a twisting shaft passing through said member, one face of said member formed with integral interruptions, a disk slidably keyed to said twisting shaft, said disk having a plurality of integral interruptions and placed facing the interruptions of said member so as to engage them upon rotation of the twisting shaft, said twisting shaft continuing beyond said disk to form a swab holding loop having an opening, a locked member normally adapted to close said opening, a resilient member surrounding said twisting shaft and interposed between the disk and the locking member, one end of said resilient member touching the disk for exerting pressure of the disk on said member, and the other end of said resilient member touching the locking member for holding the same over the opening of the swab holding loop.

2. A device of the class described comprising a U shaped member, a twisting shaft passing through both legs of said U shaped member, one face of said U shaped member formed with integral interruptions, a disk slidably keyed to said twisting shaft, said disk having a plurality of integral interruptions and placed facing the interruptions of said U shaped member so as to engage them upon rotation of the twisting shaft, said twisting shaft continuing beyond said disk to form a swab holding loop having an opening, a locking member normally adapted to close said opening, a resilient member surrounding said twisting shaft and interposed between the disk and the locking member, one end of said resilient member touching the disk for exerting pressure of the disk on said U shaped member, and the other end of said resilient member touching the locking member for holding the same over the opening of the swab holding loop.

3. A device of the class described comprising a U shaped member, a twisting shaft passing through both legs of said U shaped member, one face of said U shaped member formedwith integral interruptions, a disk slidably keyed to said twisting shaft, said disk having a plurality of integral interruptions and placed facing the interruptions of said U shaped member so as to engage them upon rotation of the twisting shaft, said twisting shaft continuing beyond said disk to form a swab holding loop having an opening, a looking member normally adapted to close said opening, said locking member being U shaped and its bottom portion straddling one leg of said loop, and slidable thereon so as to expose said opening for the insertion or withdrawal of a swab from or to said loop, said locking member having a recess in both edges of the U portions, a resilient member surrounding said twisting shaft, and interposed between the disk and the locking mem ber, one end of said resilient member touching the disk for exerting pressure of the disk on said U shaped member, and the other end of said resilient member fitting into the recess of said looking member for holding the same over the opening of the swab holding loop.
